Start here if you want better sounding files
Audio finishing is a chain of decisions: source format, cleanup, loudness, dynamics, destination, metadata, and final export. These guides teach the practical version of that chain.
Technical diagnosis
Read loudness, true peak, duration, and noise problems before changing the sound.
Sound profile
Match the chain to podcast, music, audiobook, course, restoration, or custom needs.
Compare and deliver
Use before/after listening, metadata, and export format checks before sharing.

Audio guides
Each guide is written around real creator decisions instead of abstract textbook definitions.
Formats
Beginner · 8 min
Audio format guide: WAV, AIFF, FLAC, MP3, M4A, and OGG
Learn when to use uncompressed, lossless, and lossy formats, how containers differ from codecs, and why delivery format depends on the destination.

Loudness
Intermediate · 9 min
Loudness, LUFS, true peak, and headroom

Match the sound to the job
Start with the destination. A podcast, audiobook, song, classroom lecture, transcription file, and restoration job should not all use the same processing chain.
- Speech profiles prioritize intelligibility, level consistency, and reduced fatigue.
- Music profiles prioritize tone, dynamics, peak control, and release feel.
- Cleanup profiles reduce distractions while trying to preserve the source character.
- Custom profiles save repeatable chains for shows, clients, courses, and releases.
| Content | Primary issue | Start with |
|---|---|---|
| Podcast | Uneven speech and background noise | Podcast Voice or Interview Balance |
| Audiobook | Long-form listening comfort | Audiobook Focus |
| Course | Clear lessons from varied recording setups | Lecture Clean |
| Music | Release polish and controlled loudness | Music Master or Music Glue |
| Restoration | Noise and fragile source material | Studio Clean or Noise Reduction |
| Recurring production | Consistent house sound | Custom Profile |
Glossary
Audio terms you will see in the Studio
Short definitions for the measurements and controls that matter most when comparing previews.
A loudness unit that estimates perceived volume over time.
The digital audio scale where 0 dBFS is the sample ceiling.
True peak level, estimating peaks between samples.
The distance between quiet and loud moments.
How many samples per second describe the waveform.
How much amplitude detail each sample can store.
How much data per second a compressed file uses.
The method used to encode or compress audio.
The file wrapper, such as WAV, M4A, AIFF, or OGG.
Compression that preserves the original audio data.
Compression that discards data to reduce file size.
Distortion caused when a signal exceeds available headroom.
A processor that controls peaks near the output ceiling.
A processor that reduces harsh sibilance in speech or vocals.
A filter that removes low-frequency rumble below a chosen point.
Metadata fields commonly used in MP3 files.
